APPARATUS FOR BURNING OIL..

SPECIFICATION forming part of Letters Patent No. 245,062, dated August 2, 1881.

' Application led March 14, 1881. (No model.)

A To all whom 'it may concern Be it known that. I, FREDERICK UROCKER,

of Olean, in the county of Oattaraugus andl State of New York, have invented -new and useful Improvements iii-Apparatus for Bnrning Oil," of which the following is a specifica-V tion, reference being had to the accompanying drawings. Y

This invention relates to an apparatus for 1o burning crude petroleum and similar liquid fuel in furnaces for the purpose of generating heat.'

The invention relates more particularly to an oil-burning apparatus in which the 4liquid fuel is burned in a shallow pan, and it has for its. object to produce a complete combustion of the liquid fuel by au even distribution of the air-supply over the 'surface of the fuel which is contained in the pan, and to so construct the apparatus that its operation can be easily regulated and controlled.

The invention consists of the construction and arrangement of the device wherebythese results are attained, as will be hereinafter fully 2 5 set forth.

' In the accompanying drawings, Figure 1 is a longitudinal section, and Fig. 2 a cross-section, of my improved apparatus. Fig. 3 is a top-plan view thereof. Fig. 4 is a sectional 3o elevation, cn an enlarged scale, o'f one of the air-distributing pipes. Fig. 5 is a horizontal section in linea: Fig. 4t. Fig. 6 is a top-plan view, and Fig. 7 a bottom-plan view, of the movable head of one of the air-distributing pipes. Fig. Sis a sectional elevation of the air-supply apparatus.

Like letters of reference refer to like parts in the several figures.

A represents the pan in which the liquid 4o fuel is burned,1and B a larger pan, in which the pan A isarranged so as to leavean airchamber, O, between the bottoms and side plates of both pans. The bottom a of the upper pan is provided with legs a', which rest 4 5 on thebottom b of the lower pan and serve to keep the two bottom plates at the proper distance apart.

The vertical side plates, c2, of the upper pan, A, are -provided with lugs or projections a?, 5o which bear against the vertical side plates,

of the lower pan and serve to form air-passages c between the side w. lls of the two pans, whereby the overheating of these side walls is prevented.

D represents a siphon, whereby a mixture of steam and air is injected into the chamber O.

d represents the steampipe of the siphon, which is provided with a stop cock or valve, d', whereby the force of the steam-jet is regulated.

c represents one or more openings through 6o which the external air is dra-wn into the siphon by the steam -jet and driven into the chamber C.

j' represents vertical air-distributing pipes or nozzles, whereby the air is delivered in nu- 6 5 merous fine streams upon the surface ot' the burning oil in the pan A. The pipesj'rise from the bottom a of the pan A and extend above the level of the oil in the same. Their lower ends communicate with the chamber O 7o below the pan A, and their upper ends are covered with a disk, Gr, whereby the air-current is divided and distributed.

The disk G is provided with a stem, g, having four or any other suitable number of wings, 7 5 which lit snugly in the bore of the pipe f and divide the air-current into a corresponding number ot" streams. The disk Gr is provided with a corresponding number of fine openings,

h, extending upwardly through the disk, and 8o with a corresponding number of ribs, t', formed on the under side of the disk and resting on the upper end of the pipe f. l lhe ribs t form shallow openings t" between them', from which the air issues in a lateral direction. The lower 8 5 side of the disk Gr is preferably inclined downwardly to give theseair-currents a downward direction toward the surface of the burning liquid. The disks G rest upou the open upper ends of the pipes f, and are secured in place by 9o wires j, which are attached to rods J under the bottom of the pan A.

y The discharge-apertures of the air-distributing pipes fare alternately placed at a higher and lower level,to prevent the lateral air-currents issuing from the same from interfering with eachother, and to prevent the accumulation of coke upon the air-pipes by directing the air-currents upon the heads of the pipes in various directions. toc

The crude petroleum or other liquid fuel is supplied to the pan A by means ot' a suitable pipe, Ir, and the supply is regulated by means of a stop-cock, l.

Itis obvious that any other suitable air-propelling mechanism-such as a rotary fan or an air-pump-may be employed instead of the steam-Siphon for injecting air into the chamber C; but I prefer to employ a steam-Siphon, as shown, forthe reason that a mixture of steam and air is conducive to the production of a high temperature.

My improved apparatus is arranged in the furnace in any suitable and convenient inanner if the furnace is a stationary structure or a movable structure which does not materially change the horizontal position of the pan when in use; but when the apparatus is employed for heating marine steam-boilers, for instance, the apparatus is suspended by a universal joint in the manner ot' a mariners compass, so that the pau will always retain a horizon tal position. \Vhen the apparatus is so arranged the air and oil supply pipes are connected with their respective pans by iieXible tubes or by pipes so jointed as to permit of the free movement of the apparatus. The air and steam which are injected into the apparatus are distributed by the chamber C to the different pipesf, andthe current passing through each pipe is again subdivided and delivered upon the surface of the oil in several iine streams. This secures an even and uniform distribution of the air-supply over the entire surface of the burning liquid and insures a complete combustion of the gases which are generated. The intense heat generated above the burning liquid vaporizes the upper stratum ofthe liquid, and the air-jets commingle with this vapor or gas and canse a complete combustion thereof. The oil in the pan is generally kept at a height not exceeding a quarter of an inch.

openings t" between the wings,

I claim as my invention- 1. The combination, with a pan, A, of air pipes or nozzles f, provided in their sides with air-disch arge openings fi', which deliver the air downwardly upon the surface of the burning liquid, and having their tops provided with openings la, which discharge currents of air upwardly,where they com mingle with and burn the combustible gases which escape from the burning liquid, substantially as set forth.

2. The combination, with an air-delivery pipe, ,of the disk G, provided with a winged stem, g, and air-openings z" below its overlapping head, between t-he win gs of the stem, substantially as set forth.

3. The combination, with an airdelivery pipe,f, ofthe disk G, provided with ribs i, airand air-openings L, extending upwardly through the disk, substantially as set forth.

4. The combination, with the inclosing-pan B, of the inclosed pa-n A, provided with legs a', resting on the pan B, and forming an airspace, C, and having upturned sides provided with ribs a3, which t against the upturned sides of the pan B and form air-passages c, and air-nozzlesf, formed with the pan A and communicating with the air-space C, substantially as set forth. 5. In an oil-burning apparatus, the combination, with a pan, A, of air-delivery pipesf, having their discharge-openings arranged alternately' at a higher and lower level,whereby the lateral air-currents are prevented from interfering with each other and the deposit of coke is prevented, substantially as set forth.
